Abstract

The invention discloses a novel double-action hip joint prosthesis. The novel double-action hip joint prosthesis mainly comprises an acetabular cup, a polythylene liner, a locking ring and a femoral head and is characterized in that a circle of groove is formed at the bottom of the polythylene liner; firstly, the femoral head is put into a ball socket of the polythylene liner, and then the locking ring is put into the groove of the polythylene liner and is arranged at the upper end of the femoral head; and the polythylene liner is externally arranged in the acetabular cup. The novel double-action hip joint prosthesis has the beneficial effects of being capable of solving the risk problem of dislocation of the femoral head in polythylene liner, not only being convenient to implant during operation, but also avoiding the dislocation risk of the femoral head after operation; and due to adoption of the novel double-action hip joint prosthesis, relatively good initial fixation and good long-term fixation of the femoral head in the polythylene liner are achieved, and the femoral head is convenient to install.

Description

technical field [0001] The invention relates to a prosthesis similar to human bone joints, in particular to a novel double-moving hip joint prosthesis. Background technique [0002] Artificial hip replacement refers to a prosthesis similar to human bone joints made of metal materials with good biocompatibility and mechanical properties. The artificial joint is replaced by surgical methods on the articular surface destroyed by disease or injury. It is to remove the lesion, remove the pain, and restore the activity and original function of the joint. Artificial joint replacement has the advantages of better joint movement, early mobility, and reduced complications of long-term bed rest for elderly patients. In developed countries in Europe and the United States, artificial joint replacement surgery has become one of the most common operations. In recent years, the development of hip replacement in China is also very fast. In recent years, in developed markets in Europe and t...
